Medical Device Enhanced by Advaced Miniature Diaphragm Pump and Micro Vacuum Pump

To meet consumer demand for a compact, energy-efficient blood-analysis system, a leading medical-device manufacturer turned to Hargraves Technology, www.hargravesfluidics.com, to advance their product technology. By applying more efficient motors and advanced pump-head technology, Hargraves developed a micro diaphragm vacuum pump and compressor that halved power consumption versus previous-generation blood analyzers.

The CTS miniature diaphragm pump and micro vacuum pump is used to transport air and gase measures just .80 inch (20.3 mm) wide by 1.74 inches (44.2 mm) long by 1.27 inches (32.3 mm) high, yet delivers up to 2.5 lpm unrestricted flow, pressure to 24 psig, and vacuum service to 20-in. Hg. Three configurations include: brushless dc motors for long life, brush motors for low cost, and coreless motors for maximum energy efficiency. All are available in 6, 9, or 12-Vdc versions. Operating current varies from 50 to 500 mA, depending on motor type, voltage, flow, and pressure requirements.

The single-head micro diaphragm pumps, vacuum pumps and compressors feature an advanced proprietary diaphragm elastomer for long life and increased fluidic operation. Ports are barbed to handle 1/8-in. flexible tubing. The CTS micro diaphragm compressors and vacuum pumps are dynamically balanced to minimize noise, operating at levels as low as 45 dB. The unit is suited for use with most gases over an operating temperature range of 5 to 50°C. The oil-free designs maintain system purity, and are commonly used on FDA-approved systems.
